Hi tonnytonny,
Very simple and interesting.
In google translate it says:"Pretty big pop noise will be appeared at the beginning of the first song, ... " but not sure whether there is pop/crackle after first track. Do you have after first track?
Also http://www.diyaudio.com/forums/twisted-pear/260950-dsd-initialization.html here page 2 it is stated that its a general player issue. Have a look at that thread. Don't remember what was the user using as player (foobar etc.) and source (PC etc.)... Also what you are using as source and player.
Also how is the sound, how would you describe or compare to something else?

I have been trying to find some documentation on the i2C interface. I believe the amanero can be used via usb/i2c to control an ES9018 DAC? I would like to try this on my Quanghao's Hi-END DAC to have both USB and IR control of volume and source. I plan on using linux.

it is very simple. in a config tool you have events and you can appoint command which correspond to them. You can setup bits for write in some registers for any i2c address. I now do the project on Arduino which according to i2c DAC operates and brings information to LCD. consider that i2c at amanero 3.3v

I am testing Amanero with native DSD (no DoP) in Linux. Now this is possible.
See https://github.com/lintweaker/xmos-native-dsd
I have recompiled linux kernel and alsa-lib with the patches adding this to quirks.c
Code: 
/* Combo384 Amanero */
    case USB_ID(0x16d0, 0x071a):
        if (fp->altsetting == 1)
            return SNDRV_PCM_FMTBIT_DSD_U32_LE;
        break;

I have also compiled mpd-dsd.

The only problem is that I have only the right channel playing (with some noise) but the left channel is mute. This with Native (non DoP) DSD.
Using DoP format both channels are playing right.

Remember that my Amanero card is connected directly to a passive filter (without DAC).

Some suggestions?
